Incremental Nordic Leg Curl Developer and Glute-Ham Developer Combination

ABSTRACT

This invention is an exercise device on which a human can perform glute-ham raises and six different versions of a Nordic leg curl, the six different versions of the Nordic leg curl each beginning with the knees existing flexed to a unique degree, the thighs resting against a padded support such that the hamstrings are mostly disengaged, the shins resting against a padded support, the ankles trapped between two padded supports, and the surfaces of the feet or shoes pressing against a solid surface.

BACKGROUND OF THE INVENTION

This invention is a device on which a human can exercise via performingglute-ham raises and multiple versions of the Nordic leg curl. Aglute-ham raise is an exercise constituted by a person simultaneouslyperforming the three actions of: keeping the spine, hips, and ankles inneutral positions, keeping the fingers, wrists, elbows, shoulders, andall the portions of the body below the knee joints stationary, andsustaining a force through the thighs such that both of the knees areconcurrently flexing or extending in a synchronized manner. A Nordic legcurl is an exercise constituted by a person simultaneously performingthe three actions of: keeping the spine, hips, and ankles in neutralpositions, keeping the fingers, wrists, elbows, shoulders, and all theportions of the body below the knee joints stationary, and sustainingforces through the Achilles tendons and shins against two separatesupports such that both of the knees are concurrently flexing orextending in a synchronized manner. The segment of the Nordic leg curlthat occurs when the knees are flexing constitutes the concentricportion of the exercise, whereas the segment of the Nordic leg curl thatoccurs when the knees are extending constitutes the eccentric portion ofthe exercise. The concentric portion of the standard form of theexercise begins while the torso is parallel to the ground and the kneesare completely extended and continues until the torso is perpendicularto the ground and the knees are flexed ninety degrees. The eccentricportion of the standard form of the exercise begins while the torso isin perpendicular to the ground and the knees are flexed ninety degreesand continues until the torso is parallel to the ground and the kneesare completely extended. The completion of one repetition of thestandard form of the Nordic leg curl consists of the completion of theconcentric portion of the exercise followed by the completion of theeccentric portion of the exercise.

There are multiple problems regarding the current devices designed toaccommodate glute-ham raises and Nordic leg curls. To begin with, adevice designed to accommodate both the Nordic leg curl and glute-hamraise does not currently exist. Furthermore, the devices designed toaccommodate the Nordic leg curl are limited to accommodating only thestandard version of the Nordic leg curl. The vast majority of humans aretoo weak to perform one repetition of the standard version of the Nordicleg curl, and due to the difficulty of the concentric portion of thestandard version of the Nordic leg curl continuously decreasing as thedegree of knee flexion increases from zero degrees to ninety-degrees,the standard version of the Nordic leg curl more thoroughly trains themuscle fibers responsible for initiating flexion of less-flexed kneesthan it trains the muscle fibers responsible for initiating flexion ofmore-flexed knees.

BRIEF SUMMARY OF THE INVENTION

This invention is an exercise device on which a human can performglute-ham raises and six different versions of a Nordic leg curl, thesix different versions of the Nordic leg curl each beginning with theknees existing flexed to a unique degree, the thighs resting against apadded support such that the hamstrings are mostly disengaged, the shinsresting against a padded support, the ankles trapped between two paddedsupports, and the surfaces of the feet or shoes pressing against a solidsurface. Due to this invention allowing a human to perform six differentversions of the Nordic leg curl that are each characterized bysubstantially unique difficulties, the easiest version of the Nordic legcurl that this invention facilitates being easy to perform for mosthumans who have little experience exercising, and the most difficultversion of the Nordic leg curl that this invention facilitates beingpossible to perform only by humans with extensive experience exercising,this invention allows humans of all different strengths to convenientlyuse the Nordic leg curl to strengthen their hamstrings. Furthermore, viautilizing this invention to perform multiple versions of the Nordic legcurl, users of this invention can train their hamstrings withoutoverdeveloping the muscle fibers responsible for initiating flexion ofless-flexed knees relative to the muscle fibers responsible forinitiating flexion of more-flexed knees.

DETAILED DESCRIPTION OF THE INVENTION

Via studying the figures included in this application, any person ofordinary skill in building and using fitness equipment could make anduse this invention without extensive experimentation.

1. A device on which a human can perform both glute-ham raises andNordic leg curls.
 2. A device on which a human can perform multipleversions of a Nordic leg curl that each begin with the knees existingflexed to a unique degree, the thighs resting against a padded supportsuch that the hamstrings are mostly disengaged, the shins restingagainst a padded support, the ankles trapped between two paddedsupports, and the surfaces of the feet or shoes pressing against a solidsurface.
